Explicitly specify sort order for mysql query?

Question

If I have:

ID | Title
1  | Shirt
2  | CD
3  | Cap
4  | Mp3
5  | Badge

If I want to sort by this order: 4, 2, 5, 3,1. Is there a way to do an sql query where you explicitly specify this? Something like:

select * from TABLE order by ID(4,2,5,3,1) ??

Answer 1

Actually, you were surprisingly close. It's a simple as:

select * from TABLE order by field(ID,4,2,5,3,1)

Answer 2

You can use a CASE in the ORDER BY as a rudimentary lookup table:

select *
from your_table
order by
    case id
        when 4 then 1
        when 2 then 2
        when 5 then 3
        when 3 then 4
        when 1 then 5
    end

Answer 3

select * from TABLE order by ID=1,ID=3,ID=5,ID=2,ID=4;

你跑了这个，让我知道你的怀疑。
